It works, although they were still some blackheads left but it came off nice and clean. And it could be easily pulled out. I've been using patch before, and it hard to pulled out. It sore my nose and there was acne after that! So it was really hard to find nose patch which can easily pulled out.

I got addicted to nose patch since I recommend my boyfriend to use tony moly nose patch. His nose which is full of black&white heads, was really clean after using Tony Moly patch. And I wanna go back to Tony Moly Nose Patch, because it fitted my nose just right.
